Apart from being an extremely well-preserved reference 105.012-66 displaying all the correct attributes, the present watch is a completely intriguing and historically interesting specimen. Turning the watch reveals a caseback that is engraved "CHARLES E. CARLSON" and "U.S.N. B633436". Closer inspection and research reveals a newspaper clipping stating that Charles E. Carlson indeed served aboard the USS Gunston Hall in the Pacific Ocean off Vietnam and the Philippines. His address was ETR3 Charles Carlson, B-633436 - the exact number engraved on the watch. We can thus deduce that this watch was worn by Carlson during his time serving the Navy. While not an official "issued" military wristwatch, the provenance behind this timepiece is fascinating.

Another noteworthy detail is the correct "Dot over 90" bezel, which is preserved in excellent condition, as well as the correct twisted flat lugs displaying a flat top and small step, which can only be found on 105.012-66 "CB" cases. Most existing examples today do not retain this feature as polishing would have dulled the angles. Even the crystal is the correct early generation variant.

Omega's rich history begins with its founder, Louis Brandt, who established the firm in 1848 in La Chaux de Fonds. In 1903, the company changed its name to Omega, becoming the only watch brand in history to have been named after one its own movements. A full-fledged manufacturer of highly accurate, affordable and reliable watches, its sterling reputation enabled them to be chosen as the first watch company to time the Olympic Games beginning in 1932. Its continued focus on precision and reliability ultimately led their Speedmaster chronograph wristwatch to be chosen by NASA in 1965 — the first watch worn on the moon.

Key models sought-after by collectors include their first, oversized water-resistant chronograph — the reference 2077, early Speedmaster models such as the CK 2915 and 2998, military-issued versions of the Seamaster and oversized chronometer models such as those fitted with their prestigious caliber 30T2Rg.
